Dental caries is a common name for dental caries. It is a very common dental hard tissue disease, which is a chronic progressive destruction disease of tooth enamel, dentin or cementum under the influence of many external factors, mainly bacteria.

Dental caries is a disease with a long history. The ancients in China, Assyrians and Babylonians all thought that dental caries were caused by insects, which was a misunderstanding caused by the conditions at that time. There are many theories about dental caries from the 2nd century BC to modern times, including chemical bacteria theory, proteolysis theory, proteolysis-chelation theory, glycogen theory and quadruple factor theory. At present, the accepted theories are mostly four-factor theories. It is pointed out that the occurrence of dental caries is related to four factors: bacteria, food, host and time, that is, the occurrence of dental caries requires sensitive host, oral cariogenic flora and suitable substrates, and these substrates must exist for enough time.

First of all, the existence of bacteria is the main condition of dental caries. Plaque is an important environment for bacteria to produce dental caries on the tooth surface. Good oral hygiene is also a condition for dental caries. Good oral hygiene can control the formation of dental plaque, thus controlling the occurrence of dental caries.

The second is food. Eating rough food has a certain self-cleaning and caries prevention effect. Eating rough food is not easy to produce rich dental plaque and accumulate more acid, so it is not easy to form dental caries conditions. However, the sucrose content in refined food is higher than that in coarse grains, and the sugar enters dental plaque, and the cariogenic bacteria in dental plaque ferment the sugar to form various acids. These acids stay on the surface of teeth for a long time, which will dissolve and destroy the hard tissue of teeth and produce dental caries. Eating sugar during tooth development, between meals and before going to bed is more harmful.

The third is the host. Host refers to the susceptibility to dental caries, and the sensitivity of host to dental caries involves many factors, such as the flow rate, flow rate and composition of saliva, the shape and structure of teeth, and the general condition of the body. Irregular, crowded and overlapping teeth are prone to dental caries. Saliva can clean teeth, and some components in saliva can inhibit dental caries and periodontal disease. Others, such as heredity, nutrition, minerals and endocrine, have certain effects on the host's caries prevention ability.

The fourth is time. The occurrence and development of dental caries is a rather slow process. The time required for carbohydrates to stay on the tooth surface, the time required for teeth to erupt and the time required for dental plaque to become cariogenic are all important factors affecting the incidence of dental caries.

Therefore, the four-factor theory attributes the interaction among bacteria, host, food and time to the basic and fundamental cause of dental caries.

How to prevent dental caries?

With the improvement of people's living standard and the increase of sugar content and intake frequency in diet, dental caries can flow, especially in children's deciduous teeth. With the extension of population life, root caries of the elderly are also increasing. All these seriously affect people's oral and general health, so the prevention of dental caries has become an important part of oral prevention. The prevention of dental caries has the following aspects:

1). Maintain good oral hygiene, brush your teeth two or three times a day and rinse your mouth after meals;

2) Regular oral health examination. In order to achieve the goal of "everyone enjoys oral health care by the year 2000", Kang Hua Stomatological Hospital (Stomatological Branch of the Second Hospital of the City) provides students with oral health examination and health consultation free of charge all the year round;

3) Preventive treatment of teeth with early caries or suspected future caries, including fluoride rubbing, pit and fissure sealing, preventive filling, etc. Only in this way can people have healthy teeth.

Dental caries is a chronic disease in which inorganic substances in hard tissues of teeth fall off and organic substances decompose, thus causing tooth tissue defects. Commonly known as tooth decay. Its occurrence is related to bacteria, diet, endocrine, heredity, oral hygiene and other factors.

Clinically, there are cavities, and eating can make people feel pain, cold, hot, sour and sweet.

Health guide:

1. Pay attention to oral hygiene: don't rinse your mouth after meals, don't brush your teeth before going to bed, and food remains in your teeth, which creates good conditions for bacterial activities and makes your teeth suffer from corrosion and damage. Gargling can remove food residue and some soft dirt, and reduce the number of bacteria. Rinse your mouth after every meal. The correct way to gargle is to put the solution into your mouth, keep your mouth closed and encourage your cheeks and lips, and repeatedly impact all parts of your mouth with water. Brush your teeth 3 minutes after meals, 3 minutes each time, 3 times a day. If you have difficulty, brush your teeth 1 time in the morning and evening.

2. Reasonable diet adjustment: Eating rough food requires a lot of chewing power, and the tooth surface is easy to clean, and food residues and bacteria are not easy to stay on the tooth surface. Advocate eating coarse, cellulose-rich wear-resistant food and chewing it fully. Eat less sugar and sweets, and sucrose plays a decisive role in the occurrence of dental caries. It is forbidden to eat sweets and snacks before going to bed, because the residual sugar in sweets is not easy to be completely removed. Eat a wide diet, not partial eclipse, eat more fresh fruits and melons and supplement vitamins. Eat more fluorine-containing foods, such as milk, carrots, eggs, tea and so on. Develop the habit of drinking tea, and advocate the method of gargling with tea to prevent dental caries. Experiments have proved that drinking tea can really improve the ability and resistance of tooth caries prevention.

Dental caries, commonly known as tooth decay, is a very common disease with a high incidence. Dental caries can occur at any age, especially in teenagers. Its etiology is complex, which is related to bacteria, sugar in food and the body's resistance to dental caries. It often occurs on tooth surfaces that are difficult to keep clean, such as punctate gaps, cracks and adjacent surfaces of teeth.

Dental caries is a chronic progressive disease, and its early symptoms are not obvious, so it is often not easy to be taken seriously and delayed treatment. If not treated early, dental caries will cause severe toothache when they reach the pulp, and then it will cause periapical periodontitis and osteomyelitis of the jaw, which will affect the whole body. Therefore, dental caries must be prevented and treated early.

prescription

1. Dental caries is commonly known as "tooth decay", and the early symptoms are not obvious. Only when it comes to cold, hot, sour and sweets do teeth feel sour. Anyone with the above symptoms should go to the hospital.

2. Some patients mistakenly think that they can't fill their teeth when their toothache is severe, which often delays the opportunity and loses the best treatment opportunity. The more painful it is, the more it should be treated in time. Any toothache should be treated as soon as possible.

3. Without early treatment, dental caries will corrode the nerves inside the teeth, leading to inflammation of the teeth nerves and severe pain. The so-called "toothache is not a disease" is wrong. If toothache is not treated in time, it will affect health and cause many adverse consequences.

Filling teeth is the main medical method to treat dental caries, and many patients are afraid of the pain of drilling teeth, thus delaying treatment. With the development of medical treatment, the advanced high-speed turbines are used in general hospitals at present, and there is water mist when drilling teeth, so there is little pain.

You can't eat for 2 hours after filling your teeth. If you find pain or discomfort after filling your teeth, you should go to the hospital for a follow-up visit the next day.
